T 0 all whom it may concern: I I

Beit known that we, JOHN Balmowooo and THOMAS BRANDWOOD, subjects of theof Great Britain Bury, ,in the county of Lancaster, England, haveinvented certain 'Improvements in and Relatin to the Bleach ing, Dyeing,or Other Fluid Treatment of arns Wound inthe Form ofCheeses, of 10 whichthe following is a specification.

. In-thespecification to British LettrsPat: ent No. 551 of 1913 grantedto the present applicants. and another, there is described 7 andclaimedan apparatus-for the. dyeing upon hollow and perforated ams. Suchapparatus,- consists of a closed receptacle I provided inter alia with acentral rotatable shaft carrying at its upper end radial-arms the freeend of each 'ofwhich arms is pro-' vided with screws which are adaptedto screw down upon the end of a beam to'close such end and press theother end of said beam upon a seat surroundin a liquor out- I beam andthence through the beam seat-to be returned to the receptacle, or thedirection of pump ing may be reversed 7 The apparatus referred tofulfils excellently theobject for which it was designed,

viz: the dyeing of yarns wound upon beams, each beam being one singleunit placed within the'dyeing her. It is not however suitable for thedyeing of yarns wound in smaller units than a beam, for instance,cheeses, as such dyeing is at present carried out commercially, and thispresent inven-.

.tion has forobject a form of container for yarn cheeses, with .specialdisposition of the parts of said container which will allow ofpreliminary compression of the cheeses to a uniform density and thesubseque'nt dye dyeing re-' ing of the said cheeses in a beam ceptacleof the type just referred 'to,'a number of cheeses being packed withinthe con tainer so that each container [will fornr'a single compact unitfor placing upon a liq- -uid tight seat of the dyeing receptacle. The

upper end of each of the said units is arranged so that the screwscarried by the. radial arms'may screw within the upper end of such unitto allow of the latter being and Ireland, and I arns wound through thethe said bottom .plate. I I tubes may be pfjanysuitable metalor alloywhich willlwithstand the-action of'any liqsecurel held whilst fluid isbeing circulated throughout the whole of the yarn ofjthe cheeses. I .Ourinvention will nowbe fully'described with reference'to theacc ompanyingdraw- I in .whereinz' I igure 1 is'a. verticalsection of the containerwith cheeses; and. i Figure -2 a plan. Referring to Figures 1 and 2, 1is a bottom plate having formed thereinthe chamber 2- and provided withthe tubular boss 3.

4 is a vertical rodsecured to the upper-face of the bottom plate 1 inany convenient manner; in the illustration .it is shown as-being,screwed into an orifice in the upper part of the bottom plate 1 and;secured in place by the nut 5. This vertical rod isscre'we'd externallyfor approximately half of its length as shown, the thread beingpreferably a square thread, with a nut 6 fitted upon the said screwedportion. 7 are perforated tubes placed parallel't'o and symmetricallyaround the central rod 4, being secured to the .-upper. surface ofth'ebottom plate 1 in any known manner and opening into the chamber .2 of

These perforated uid With which the cheeses may be treated and each ofthem is provided {with a stopper 8 at its upper extremity. Thisextremity may be however permanently closed in any other. convenientmanner. 9 are cheeses fitted upon the said perforated tubes, and 10 atoppressure plate having screw eyes 11 for lifting purposes, and orificesformed therein to'enable it to be slidden upon the central rod 4 and theperforated tubes 7. At its upper extremity the central rod 4 isinternally-threaded to receive the screwed shank of a ringfhandle'12.

'In order to prepare the container with a numberfof cheeses for dyeingas a single unit in a dyeing receptacle of the type hereinbeforereferredto, the ring handle 12 is removed and the nut dunscrewed from the 100contral rod 4. The top plate. 10 is then removed, and cheeses 9are'mounted upon each of the perforated tubes '7, one on top of theother, untilfthe container isfilled as shown I in the drawing. The topplate is then passed 1 over'the central rod 4 and the tubes 7 andscrewed upon the central down tightly against the top plate 10, any

' containers.

bottom plate rests upon the top cheeses. The nut 6 is then rod 4: andscrewed desired compression 'being thus given to the cheeses. Owing tothe nature ofthe winding of yarn in cheese form such compression 'isnecessaryfor level treatment of all the yarn-in abheese with any fluid.The desiredbeing attained by means of the handle 12 is screwed in place,

- of the arm is-then screwed down into lthe extremit of the said rod,the container thus being he (1 securely for the dyeing operation'and'atthe same time pres'seddown firmly on its seat E. Liquid may thenbe pumped into the receptacle at any convenient pressure.

' above atmospheric and, when the receptacle is filled, the

inwards through the yarn-ofallthe cheeses into the perforated tubes 7and, -the upper ends of these tubes being closed, will be forced intothe chamber 2 of the bottom plate 1, and thence through tubular boss 3back to 1 the liquor tank. The flow of liquid maybe reversed if desired.Y

' The cheeses in the container may be treated with air or any otherdesired material after the liquor treatment,- and when the wholeoperation is completed, the screw J may be released from the arm G movedaway from the central rod 4:. The ring handle 12'is' then inserted, andthe container is lifted from liquid will be forced radially thereceptacle, for the removal of the cheeses therefrom,

By the use of a receptacle provided for six-beams as shown in the priorspecification: for the dyeing of six compact units composed of yarncheeses as just described, a .very large 'quantitv of yarn in the formof cheesesfmay be dyed simultaneously, all of the cheeses being ofuniform density and being treated at equal fluid pressure. Level dyeingand a reduction in dyeing cost are thus assured. It desired however, aless or greater number than'six' of these compact units may be treatedsimultaneously, accordin to the capacity of the receptacle.

Vhat we claim as our invention and desire to secure by Letters. Patentis A-container for yarn cheesesto be subiected to bleaching, dyeing orother treatment with fluids in a closed receptacle and at a pressurehigher than atmospheric, said container comprising. a bottom plateprovided with an internal chamber, means for placing said bottom plateon a liquid tight seat around a liquor opening commuhicat.

ing with the said internal chamber, a'central rod vertical to-the bottomadapted at its upper end to receive a lifting handle or alternativelscrewing down means to press the bottom p ate on its seat, verticalperforated tubes adapted to receive cheeses of yarn and opening to theinternal chamber of the bottom plate, and a top pressure plate slidingon the central rod and tubes,

with means for applying pressure thereto to compress the cheeses betweenthe top and bottom plates to a uniform density.

In testimony whereof we have hereunto set our hands.
